Katy Perry introduced her brand spankin’ new single, Roar, in full on Sunday, and in honor of the momentous occasion, made sure to celebrate by opening up about the track’s motivations!

She revealed that her latest song is uplifting on a deeper, more personal level:

Katy explained:

"Strangely enough, as much as I'm so loud and proud about my music, sometimes in other aspects of my life I became very introverted and didn't feel like I could say what I meant, and I got to a boiling point and it would just boil over a little bit… "So 'Roar' was a song I wrote about really standing up for myself, finally, and hopefully people are going to adopt that same message… I'm bringing my A-game I'll tell you that."

A new Bill Cosby accuser's story of how he allegedly sexually assaulted her after drugging her drink is horrifying.
